The VFF Flow Meter was designed for use in Chemical Injection applications or those that require high pressure tolerance, low flow capabilities, and corrosion resistance. VFF meters are available in a wide range of flow rates; as low as 0.01 gal/hr up to 634 gal/hr. Practical applications include:

Offshore Chemical Injection
Hydraulic line monitoring for well control valves and leak detection
Wash water measurement and general metering of low and high viscosity fluids
Subsea Chemical Injection and hydraulic fluid measurement
